I turned over when I heard the knock on my door. I looked over at the clock and was disappointed that it was already 8am. Mom opened the door just a little at first poking her head in to tell me that she was making pancakes and that they (her and my sister Vicky) had already showered and that it was free for me. I told her thanks and then asked if she would close the door. Mom appeared a little disappointed. I think that she wanted to come in and sit on my bed for a little while.
After my shower I dressed in my usual summer morning attire...a pair of boxers no shirt. As I walked into the dinning room I could hear their argument fade as they noticed my arrival. Mom looked at me and asked if I'd like to put on a shirt before sitting down for breakfast.
Vicky looked me up and down and said, "I'm not complaining bro."
I looked at mom in her usual long robe and then to Vicky who was surprisingly wearing a very similar one to mom's. I asked Vicky is she raided mom's closet.
Vicky said, "mom thought that I needed to cover up a little this morning."
"Well, I don't like it at all. What did you have on before?" I asked.
Vicky stood up and said, "I still have it on under this blanket (referring to her borrowed robe)." She started to unzip the robe at the neckline but the zipper got stuck in between her breasts.
I quickly jumped up and offered my assistance. I walked around back of her as she stood facing mom. Mom was quietly eating and watching us.
My dick was slowly growing against my sister's ass as I deliberately reached around to the front of my her body slowly sliding my hands up the front and over her breasts the the zipper in the middle. I watched mom's face turn red as my hands palmed my sister's breasts (appearing somewhat accidental on my part). I grabbed a hold of the zipper and worked it free while slowly lowering it to her mid-thigh area.
My sister leaned her head back slightly to thank me by placing a kiss on my cheek. I laughed and told her that it was my pleasure. Vicky started to shed the robe off of her shoulders and I stopped her by saying that I would do that.
Mom watched as I unveiled my sister's body in front of her. Vicky stared at mom as my hands grabbed the collar on each side of the robe and slid my hands down back over her silk camisole covered breasts and rock hard nipples. My thumbs pressed a little while passing over my sister's nipples. As the robe fell to the floor I stepped back to admire my sister's nightie. She was in an off white silk camisole top that was very loose and came down to her panty line. On the bottom she had on a pair of matching off white silk panties with a little bit of lace in the front so that one could see that she had dark pussy hair. Still standing behind Vicky I was running my left hand up and down under the back of her top. I whispered to Vicky to play along.
I looked over at mom and asked, "what's was wrong with it? It's not like Vicky is wearing a thong or anything", I said grinning.
I then started playing fashion consultant as if Vicky was my live model while still standing behind her concealing my raging cock and burying it into my sister's panty covered ass cheeks. I moved my head around to the front and pointed out the very detailed needlepoint work of the lace on my sister's panties. I could feel Vicky's hot breath on the back of my neck as I positioned myself lower to touch the lace area of my sister's panties. I took my index finger and ran it along the inside eadge of my sister's panties next to her pussy. The tip of my finger gently sliding inside of the material. I slid my finger all the way from the front to back. I could feel the edge of her lips and a few hairs. I could also feel how wet she was.
Mom just looked disgusted and told me to stop. My sister loved it as I reached up and pointed out the V-neckline. As I described the careful yet seductive forethought it took to make this type of neckline I ran my index and middle fingers along the edge in between the middle of her breasts. The material was thin but not sheer.
Mom spoke up and said, "you shouldn't be touching your sister like this".
I looked at mom and said, "oh really....why don't you shut the fuck up and eat your delicious pancake with SYRUP".
